Abstract

PURPOSE: An index rotating-type UV curing and molding device is provided to reduce the size of the device because the device can be installed in a narrow space by performing work on the top of a rotating turntable. CONSTITUTION: An index rotating-type UV curing and molding device comprises a turntable(20), a curable resin feeding unit(30), a laminating unit(40), and an UV curing unit(50). Molds of the turntable are fixed on the top of a device frame(10) at regular angles. A dispenser(31) for feeding UV curable resins is mounted on the curable resin feeding unit and moves forward and backward. The curable resin feeding unit feeds the UV curable resins to the mold. If the curable resin feeding unit feeds the UV curable resins to the molds and the molds are rotated at a predetermined angle after covering the top of the molds is covered by films, the laminating unit flatly spreads the curable resins by pressing the top of the films with a roller(41). If the turntable is rotated on the laminating unit at the predetermined angle, an UV lamp of the UV curing unit moves back and forth to cure the curable resins.

Index rotating ultraviolet curing molding apparatus according to a preferred embodiment of the present invention is shown in FIGS. Index rotating type UV curing molding apparatus according to the present invention is a turntable 20 and the turntable 20 is fixed to the mold 21 at a predetermined angle in the upper portion of the apparatus frame 10 and the rotating shaft is connected to the index motor 60, the turntable ( 20) the curing resin supply unit 30 for supplying the ultraviolet curable resin to the upper side of the mold 21 fixed to the turntable 20 is mounted to one side and the dispenser 31 for supplying the ultraviolet curable resin forward and backward; When the ultraviolet curable resin is supplied to the mold 21 from the curable resin supply unit 30 and the film is covered on the upper surface of the mold 21, and then rotated at a predetermined angle, the cured resin is unfolded in an uneven manner. The laminating part 40 installed so that the roller 41 which presses the back and forth and the turntable 20 rotates at a predetermined angle in the laminating part 40 are ultraviolet lamps 51 for curing the cured resin. Jin consists of a UV curing unit (50) mounted to. Here, the mold 21 is installed every 120 degrees, and the index motor 60 is controlled so that the turntable 20 stops every 120 degrees.

The curable resin supply unit 30 may include the dispenser 31 having a nozzle installed to supply the curable resin to the mold 21, a rod 32 on which the dispenser 31 is fixed, and the rod 32. A timing belt case 34 having a timing belt (not shown) for linear reciprocating transfer and a driving motor 33 for driving the timing belt.

In addition, the laminating unit 40 is a guide frame 42 installed in parallel in two rows fixed to the device frame 10, and the roller frame 43 is installed so that the front and rear linear reciprocating movement to the guide frame 42. And a lifting cylinder 46 installed on the roller frame 43 and provided with the roller 41 at a lower portion thereof, and a lifting cylinder 46 installed at a lower portion of the lifting cylinder 46 to pressurize and roll the upper surface of the mold 21. The roller 41, the roller frame 43 is connected to the timing belt 45 for transporting the roller frame 43, and the drive motor 44 for transporting the timing belt 45. .

On the other hand, the ultraviolet curing unit 50 is an ultraviolet irradiator 51 is provided with an ultraviolet lamp to irradiate ultraviolet rays, a guide frame 52 for guiding the ultraviolet irradiator 51 to reciprocate linear movement, and the guide The feed screw 53, which is fitted to the frame 52 and partly engaged with the ultraviolet irradiator 52, and supplies the rotational driving force of the conveying screw 53 to control the conveyance of the ultraviolet irradiator 51. It consists of a motor 54. Here, the ultraviolet irradiator 51 is provided to be elevated. That is, the lifting cylinder is provided in the ultraviolet irradiator 51 and installed so that lifting is possible.

Referring to the operation of the index rotation type UV curing molding apparatus according to the present invention.

First, when the turntable 20 is rotated by 120 degrees and the new mold 21 is at the lowermost position in FIG. 1 and at the position of the cured resin supply unit 30, the driving motor 33 operates to transfer the rod 32. The dispenser 31 supplies the cured resin to the upper surface of the mold 21. After supplying the cured resin, it returns to its original position by the operation of the drive motor 33 of the dispenser 31. When the cured resin is supplied to the mold 21, the worker covers the film at that position.

Thereafter, the turntable 20 is rotated again by 120 degrees. When the turntable 20 is rotated, the motor 44 is operated to advance the roller 41. At this time, the roller 41 is in the state raised up by the lifting cylinder 46. Therefore, it does not contact the film on the metal mold 21 at this time. At maximum advance, the lifting cylinder 46 lowers the roller 41, and the roller 41 is pressed onto the film. In this state, the motor 44 operates to return to the original position in the state where the film is compressed by the roller 41. Therefore, the cured resin in the lower part of the film is completely uncured and thus completely penetrates into all the spaces formed by the mold 21.

After that, when the turntable 200 is rotated 120 degrees again, the ultraviolet irradiator 51 irradiates and hardens the cured resin supplied to the mold 21 while advancing back and forth according to the driving of the motor 54. The ultraviolet irradiator Numeral 51 indicates that the motor 54 rotates the feed screw 53 forward and backward.

When UV curing is performed, the turntable 20 is rotated 120 degrees to return to the cured resin supply unit 30. The worker then peels off the film before the cured resin is supplied by the dispenser 31. Of course, the cured resin hardened in the shape of a mold is imprinted on the film.

In this way, the cycle is repeated to produce products continuously without stopping.

The present invention described above is not limited to the above-described embodiment and the accompanying drawings, and various substitutions, modifications, and changes are possible within the scope without departing from the technical spirit of the present invention. It will be evident to those who have knowledge of.
